2017-05-15spl: add support to booting with ATFKever Yang
ATF(ARM Trusted Firmware) is used by ARM arch64 SoCs, find more infomation about ATF at: https://github.com/ARM-software/arm-trusted-firmware SPL is considered as BL2 in ATF terminology, it needs to load other parts of ATF binary like BL31, BL32, SCP-BL30, and BL33(U-Boot). And needs to prepare the parameter for BL31 which including entry and image information for all other images. Then the SPL handle PC to BL31 with the parameter, the BL31 will do the rest of work and at last get into U-Boot(BL33). This patch needs work with patches from Andre for SPL support multi binary in FIT. The entry point of bl31 and bl33 are still using hard code because we still can not get them from the FIT image information.

2017-05-08spl: make image arg or fdt blob address reconfigurableVikas Manocha
At present fdt blob or argument address being passed to kernel is fixed at compile time using macro CONFIG_SYS_SPL_ARGS_ADDR. FDT blob from different media like nand, nor flash are copied to the address pointed by the macro. The problem is, it makes args/fdt blob compulsory to copy which is not required in cases like for NOR Flash. This patch removes this limitation. Signed-off-by: Vikas Manocha <vikas.manocha@st.com>

2017-03-16spl: Add spl_early_init()Eddie Cai
At present malloc_base/_limit/_ptr are not initialised in spl_init() when we call spl_init() in board_init_f(). This is due to a recent change aimed at avoiding overwriting the malloc area set up on some boards by spl_relocate_stack_gd(). However if CONFIG_SPL_STACK_R_MALLOC_SIMPLE_LEN is not defined, we now skip setting up the memory area in spl_init() which is obviously wrong. To fix this, add a new function spl_early_init() which can be called in board_init_f().

2016-10-06spl: Make spl_boot_list a local variableSimon Glass
There is no need for this to be in the BSS region. By moving it we can delay use of BSS in SPL. This is useful for machines where the BSS region is not in writeable space. On 64-bit x86, SPL runs from SPI flash and it is easier to eliminate BSS use than link SPL to run with BSS at a particular cache-as-RAM (CAR) address.

2016-06-26common: Pass the boot device into spl_boot_mode()Marek Vasut
The SPL code already knows which boot device it calls the spl_boot_mode() on, so pass that information into the function. This allows the code of spl_boot_mode() avoid invoking spl_boot_device() again, but it also lets board_boot_order() correctly alter the behavior of the boot process. The later one is important, since in certain cases, it is desired that spl_boot_device() return value be overriden using board_boot_order().

Make spl_*_load_image() functions return a value instead of hanging if a problem is encountered. This enables main spl code to make the decision whether to hang or not, thus preparing it to support alternative boot devices. Some boot devices (namely nand and spi) do not hang on error. Instead, they return normally and SPL proceeds to boot the contents of the load address. This is considered a bug and is rectified by hanging on error for these devices as well.

2015-06-10arm: spl: Add an API to detect when U-Boot is started from SPLSimon Glass
For secure boot systems it is common to have a read-only U-Boot which starts the machine and jumps to a read-write U-Boot for actual booting the OS. This allows the read-write U-Boot to be upgraded without risk of permanently bricking the machine. In the event that the read-write U-Boot is corrupted, the read-only U-Boot can detect this with a checksum and boot into a recovery flow. To support this, add a way to detect when U-Boot is run from SPL as opposed to some other method, such as booted directly (no SPL) or started from another source (e.g. a primary U-Boot). This works by putting a special value in r0. For now we rely on board-specific code to actually check the register and set a flag. At some point this could be generalised, perhaps by using a spare register and passing a flag to _main and/or board_init_f(). This commit does not implement any feature, but merely provides the API for boards to implement. Signed-off-by: Simon Glass <sjg@chromium.org>
